Title: Electric source circuit
Inventor: MANFURETSUDO ARUBATSUHA
IPC: H02M3/156
Filed: 1988-07-07
Abstract: PURPOSE: To suppress undesired high frequency voltage by connecting an AC power supply with a power storage means and operating a switch which takes out power only during the interval other than the connecting time interval. CONSTITUTION: A control circuit 13 at a power supply section 7 turns a transistor (Tr) 10 on in switching mode. A low resistance measuring resistor 31 is arranged in the connection line between a bridge rectifier 5 and a joint A and voltage drop due to a charging current is detected by means of a measuring amplifier 32. The measuring amplifier 32 generates, at the output end 33 thereof, a digital suppression signal which has a logical value of 0 when the charging current flows and a logical value of 1 during other time intervals. Consequently, an AND circuit 34 arranged in the line to the Tr 10 is turned off for a momentary interval. A disturbance is prevented from reaching an AC power supply 1 by interrupting the driving of the Tr 10 during a time when the bridge rectifier 5 is conducting thereby preventing occurrence of a disturbance.

Title: Radiator
Inventor: FUJIWARA MAKOTO
IPC: H05K7/20
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To reduce weight, without reducing radiation efficiency by forming the base of a radiator provided with the base in contact with radiating members. SOLUTION: A base 1 is made of a metal, for example, square in a plan view and formed stepwise in cross-section with the center elevated, and has a contact surface 1a in contact with a heating body 20 in the center thereof. The base 1 has a plurality of columnar fins on the other surface thereof. Heat transmitted from the heating body 20 through the contact surface 1a is radiated from the surfaces of the fins 2. Accordingly, the fins 2 provided near the outer periphery of the contact surface 1a radiate the heat transmitted from the center of the base 1 towards the outer periphery thereof to the fins 2. Since the base 1 is formed stepwise in cross-section, the surface area of the base 1 is enlarged to improve radiation efficiency. Therefore, the base 1 can be reduced in weight as compared with the base which is made in whole in the largest thickness of the base 1.

Title: Solar heat collecting device
Inventor: EBISU KOJI
IPC: F24J2/44
Filed: 1984-08-11
Abstract: PURPOSE:To shift surely refrigerant by a method wherein at an upper part of a solar heat collector the second liquid reservoir is provided, in heat collecting time the refrigerant is sacked from a heat storage tank side by lowering its vapor pressure, on the other hand, in non heat collecting time the refrigerant is returned to the heat collector by gravity. CONSTITUTION:When an evaporizer 2 is heated up by solar radiation heat, the vapor pressure of the refrigerant 10 is becoming high due to its evaporation, and a valve 15 is closed. The vaporized refrigerant, passing through a piping 4, is condensed and liquified in a heat storage tank giving its heat to the said tank. The vapor pressure in the second liquid reservoir 9 is becoming low, as heat is emitted by a radiator. Accordingly, the condensed and liquified refrigerant, passing through the check valve 12A. flows into the second liquid reservoir 9. The refrigerant in the second liquid reservoir 9 is supplied with the first liquid reservoir 1 passing through a check valve 12B. When solar heat radiation comes off, the vapor pressure in the vaporizer 2 becomes low, whereas the vapor pressure in the second liquid reservoir becomes high, therefore, the valve 15 is opened and the refrigerant is returned to the first liquid reservoir 1 by gravity.
